[0062] Please refer to Figure 1-6 , an automatic tool setting device for a grinding wheel gear grinding machine:

[0063] The bottom slide 1 is designed as a solid base, with high stability and load-bearing capacity.

[0064] The close fit between the spindle fixed seat 2 and the bottom slide 1 provides a stable spindle support.

[0065] The movable positioning seat 3 is designed to be electrically slidable left and right along the top of the bottom slide table 1, and achieves smooth and precise movement through a precise guide rail system.

[0066] The grinding wheel 8 is made of a material with high hardness and wear resistance to ensure good cutting performance even under high-speed rotation.

[0067] Tool setting drive mechanism:

[0068] The tool setting drive mechanism 5 adopts a modular design to ensure the speed and accuracy of the tool setting process.

[0069] The lateral position adjustment drive mechanism 51 and the longitudinal position adjustment drive mechanism 53 work together. Through a precise motor and lead screw system, the grinding wheel 8 is rapidly moved in the X and Y axis directions to complete the tool setting operation.

[0070] Lateral position adjustment drive mechanism:

[0071] The first drive motor 511 is a servo motor with high torque and low noise, ensuring smooth power output during startup and shutdown.

[0072] The first drive lead screw 512 is a high-precision ball screw, reducing friction and improving transmission efficiency.

[0073] The first lead screw sleeve 513 is fixedly connected to the center of the bottom of the longitudinal installation box 52 to ensure synchronization and stability during lateral movement;

[0074] Among them, the first drive motor 511 drives the first drive lead screw 512 to rotate, and then converts the rotational driving force into the power to drive the first lead screw sleeve 513 to move linearly left and right, thereby driving the longitudinal installation box 52 and the components above it to move horizontally left and right, and finally driving the grinding wheel 8, the laser emitter 6 and the laser receiver 7 to move horizontally.

[0075] Longitudinal position adjustment drive mechanism:

[0076] The second drive motor 531 is a servo motor with high torque and low noise, ensuring smooth power output during startup and shutdown.

[0077] The second drive lead screw 532 is a high-precision ball screw, reducing friction and improving transmission efficiency.

[0078] The second lead screw sleeve 533 is docked with the bottom end of the docking shaft 54 at the bottom of the grinding wheel and the laser emitter 6, enabling the two to move longitudinally following it;

[0079] Among them, the second drive motor 531 drives the second drive lead screw 532 to rotate, thereby converting the rotational driving force into the power to drive the second lead screw sleeve 533 to move linearly back and forth, and then realizing driving the longitudinal installation box 52 and the components above it to move horizontally left and right. Finally, it realizes the operation of driving the bottom end of the grinding wheel bottom docking shaft 54 and the laser emitter 6 to move back and forth. And with the docking relationship between the grinding wheel 8 and the grinding wheel bottom docking shaft 54, it can drive the grinding wheel 8, the drive shaft 54 at its top, and the grinding wheel drive motor 56 to move, and then drive the laser receiver 7 to move synchronously with the laser emitter 6, ensuring that the emitted laser always passes into the laser receiver 7.

[0080] Laser tool setting system:

[0081] A high-precision tool setting system composed of a laser emitter 6 and a laser receiver 7, by emitting and receiving laser beams. When the laser receiver 7 does not receive the laser emitted by the laser emitter 6 for the first time during the tool setting process, the tool setting operation is completed at this time, and the grinding wheel drive motor 56 can be started to drive the grinding wheel 8 to rotate, realizing the tooth surface processing operation of the gear to be machined.

[0082] The laser beam emitted by the laser emitter 6 is precisely calibrated, and can fit the edge of the gear to be machined and pass through the edge of the grinding wheel 8, realizing contactless high-precision tool setting.

[0083] Guide assembly:

[0084] The guide assembly composed of a guide rod 591 and a guide sleeve 592 ensures the linearity and stability of the entire tool setting drive mechanism 5 during the sliding adjustment process.

[0085] The design of the guide assembly takes into account wear resistance and corrosion resistance to adapt to long-term and high-frequency use.

[0086] Grinding wheel drive and positioning:

[0087] The grinding wheel drive motor 56 adopts a high-performance motor, which can provide sufficient power to drive the grinding wheel 8 to rotate at high speed.

[0088] The design of the sliding collar 58 and the longitudinal guide 57 ensures the stable positioning of the grinding wheel drive motor 56 during operation, preventing deviation or shaking.

[0089] Working principle

[0090] Position the gear to be machined between the main shaft fixed seat 2 and the movable positioning seat 3.

[0091] Horizontal movement: Start the first drive motor 511. Through the transmission of the first drive lead screw 512 and the first lead screw sleeve 513, the longitudinal installation box 52 and the components above it move horizontally left and right. At this time, the grinding wheel 8, the laser emitter 6, and the laser receiver 7 move left and right accordingly.

[0092] Longitudinal movement: Start the second drive motor 531. Through the transmission of the second drive lead screw 532 and the second lead screw sleeve 533, the grinding wheel 8, the laser emitter 6, and the laser receiver 7 follow the forward and backward displacement operation.

[0093] Laser tool setting: During the displacement process, the laser emitter 6 emits a laser beam, and the laser receiver 7 receives the laser beam. When the laser receiver 7 does not initially receive the laser emitted by the laser emitter 6, the tool setting operation is completed.

[0094] Start the grinding wheel: After the tool setting is completed, start the grinding wheel drive motor 56 to make the grinding wheel 8 rotate at a high speed, and start machining the tooth surface of the gear to be machined.

[0095] Machining process: Driven by the grinding wheel drive motor 56, the grinding wheel 8 grinds the gear.

[0096] Finish machining: After the machining is completed, stop the grinding wheel drive motor 56, turn off all drive mechanisms, clean the working area, and prepare for the next round of machining.
